The earliest I remember is being made fun of in kindergarten. It remained bad till middle school, that is when I got professional help. That was when good days started outnumbering bad days. Growing up in high school, and college was not bad, but the bad days were really bad and the good days (although in the majority) were just ok. Things got better for me because I became better at other things apart from speaking, which gave me a sense of self worth, which in turn gave me confidence to speak up. I still stutter now, but I am at peace with it and can control it to an extent. Fight on, my friend.
